Titan’s Grand Canyons

NASA JPL
We already know that Saturn’s moon Titan is an incredible world. NASA’s Cassini mission has shown evidence of a substantial atmosphere and hydrocarbon seas, leaving many to wonder if the moon harbors strange forms of life. Scientists can add a new formation to the catalog: enormous, steep canyons that are actively being carved by flowing rivers of methane, making Titan the only place in the solar system besides Earth where the surface is actively being eroded.
